1. An electronic device for a first communication device in a wireless communication system, comprising:
a processing circuit configured to:
receive channel state information reference signal with a set of reception filters;
perform channel estimation on a downlink channel from a second communication device to the first communication device;
select from the set of reception filters one or more particular reception filters corresponding to respective channel estimation results that satisfy a first predetermined condition so as to generate a subset of reception filters,
report, to the second communication device, channel state information indicating the subset of reception filters;
receive, from the second communication device, configuration information indicating one or more particular transmission filters, wherein the one or more particular transmission filters and one or more particular reception filters are reciprocal respectively; and
signal, from the first communication device to the second communication device, sounding reference signal with the one or more particular transmission filters.
